Environmental conditions

　　　 In the vicinity of location of the accident

Weather : cloudy Wind : NNE force about 13 ~ 15m/s Tidal stream : NE about 0.9kn Wave direction : NNE ~ 　 NE Wave height : about 2 ~ 3m Wave period : 4.7 ~ 5.0 second Wave speed : 7.3 ~ 7.8 m/s (14.2 ~ 15.2 kn)　　　　　　　　　　　　　　　　　　　　＜ Wave direction and wave height related directly to the capsize

＞　　　　　　　　　　　 the first wave : wave direction NNE ~ NE wave height about 3 ~ 4m 　　　　　　　　　　　 the second wave : wave direction N ~ NNE wave height about 4 ~ 5m

Probable Cause　　

　　　　 When the vessel encountered the second wave after the first wave while she was sailing on quartering sea, the vessel reduced stability on the crest of the wave.

　　　　 It caused water shipping and trapping on deck and large roll motion to starboard side due to the fishing net shift. And the vessel continued turn to starboard side to restore inclining, but the inclining increased, which led to submerging of starboard bulwark to cause the capsize.

Safety opinion

The fishing industry authority should instruct fishing industry and fishermen on risk of surf-riding, broaching and stability reduction in quartering seas to prevent recurrence of these accidents.
